Chelation-assisted olefinic C-H functionalization has been demonstrated to be a powerful method of constructing multi-substituted alkenes from simpler ones. This strategy produces complex alkenes in a regio- and stereoselective manner, followed by C-H endo- and exo-cyclometallation. Among the various directing groups developed, N,N- and N,O-bidentate directing groups are the most widely used to selectively promote C-H functionalization due to their fine, tunable, and reversible coordination with the metal center. In this review, we discuss various N,N- and N,O-bidentate directing group-assisted olefinic C-H bond functionalization reactions, including alkenylation, alkylation, arylation, thiolation, silylation, halogenation, and cyclization.
螯合辅助的烯烃C-H官能化已被证明是一种从较简单的烯烃构建多取代烯烃的有效方法。该策略以区域和立体选择性的方式生成复杂烯烃，随后进行C-H内和外环金属化。在已开发的各种导向基团中，N,N-和N,O-双齿导向基团由于其与金属中心的良好、可调节和可逆配位而被最广泛地用于选择性促进C-H官能化。在本综述中，我们讨论了各种N,N-和N,O-双齿导向基团辅助的烯烃C-H键官能化反应，包括烯基化、烷基化、芳基化、硫醇化、硅烷化、卤化和环化。
